I reset motorola surfboard sbg6580 wireless modem/router, after 20 seconds modem/router rebooted (I have it setup to search for updates upon login), system was unable to retrieve updates (I backed up configuration before resetting modem/router and restored after resetting it.) Now I changed prior mirror used gigenet.com to mit's mirror. I am starting using it right now.
